57 * 7 + 12 * 4 = 399 + 48 = 447
(27-14:2) * (17-5 * 3)= (27 - 7) * (17 - 15) = 20 * 2 = 40
55-8 * (18-3 * 5)= 47 * (18 - 15) = 47 * 3 = 141
1200:40:15 * 10-18+2= 30 : 15 * 10 - 18 + 2 = 2 * 10 - 18 + 2 = 20 - 18 + 2 = 2 + 2 = 4
32:(724-241 * 3) * 25= 32 : ( 724 - 723 ) * 25 = 32 : 1 * 25 = 32 * 25 = 800
